我在xml文件中有一行我想要动态地添加到RelativeLayout,但它总是在行的最右上方留下一个空的空格。当我在RelativeLayout父xml中设置此行时,不会留下空白空间。这是我要添加的行xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/food_nutrients_line"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1" >
<TextView
android:id="@+id/food"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:background="@drawable/edittext_no_gradient_brown_up_stroke"
android:padding="3dp"
android:singleLine="true"
android:text="name"
android:textColor="@android:color/holo_green_dark"
android:textSize="10sp" />
<TextView
android:id="@+id/units"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="@drawable/edittext_no_gradient_brown_up_stroke"
android:gravity="center"
android:paddingBottom="3dp"
android:paddingTop="3dp"
android:text="un"
android:textColor="@android:color/holo_green_dark"
android:textSize="10sp" />
<EditText
android:id="@+id/quantity"
android:layout_width="40dp"
android:layout_height="wrap_content"
android:background="@drawable/edittext_no_gradient_brown_up_stroke"
android:gravity="center"
android:hint="@string/quantity_edittext"
android:inputType="number|numberDecimal"
android:paddingBottom="3dp"
android:paddingTop="3dp"
android:textColor="@android:color/holo_green_dark"
android:textSize="10sp" />
<TextView
android:id="@+id/kcal"
android:layout_width="45dp"
android:layout_height="wrap_content"
android:background="@drawable/edittext_no_gradient_brown_up_stroke"
android:gravity="center"
android:paddingBottom="3dp"
android:paddingTop="3dp"
android:text="4"
android:textColor="@android:color/holo_green_dark"
android:textSize="10sp" />
<TextView
android:id="@+id/carbs"
android:layout_width="40dp"
android:layout_height="wrap_content"
android:background="@drawable/edittext_no_gradient_brown_up_stroke"
android:gravity="center"
android:paddingBottom="3dp"
android:paddingTop="3dp"
android:textColor="@android:color/holo_green_dark"
android:textSize="10sp" />
<TextView
android:id="@+id/proteins"
android:layout_width="40dp"
android:layout_height="wrap_content"
android:background="@drawable/edittext_no_gradient_brown_up_stroke"
android:gravity="center"
android:paddingBottom="3dp"
android:paddingTop="3dp"
android:textColor="@android:color/holo_green_dark"
android:textSize="10sp" />
<TextView
android:id="@+id/fat"
android:layout_width="30dp"
android:layout_height="wrap_content"
android:background="@drawable/edittext_no_gradient_brown_up_stroke"
android:gravity="center"
android:paddingBottom="3dp"
android:paddingTop="3dp"
android:text="0"
android:textColor="@android:color/holo_green_dark"
android:textSize="10sp" />
这是我用来动态添加行的代码:
plusButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View foodLine = inflater.inflate(R.layout.food_line, null);
LinearLayout blank = (LinearLayout) findViewById(R.id.food_nutrients_blank_line);
blank.addView(foodLine);
}
});
任何可能出错的想法?

将父布局传递到充气机我发现大部分时间都适用于此问题。
新参数是(资源文件,父级,是否要自动添加),我发现最好手动添加
inflate(int resource, ViewGroup root, boolean attachToRoot)
更新onClick
@Override
public void onClick(View v) {
LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
LinearLayout blank = (LinearLayout) findViewById(R.id.food_nutrients_blank_line);
View foodLine = inflater.inflate(R.layout.food_line, blank, false);
blank.addView(foodLine);
}
